So, as someone who lives in France, I feel it is more socially conservative and I have come across some casual sexism here which I think would be less likely to happen in the UK.
For example, when my husband and I got a mortgage, he was named on all the paperwork as the borrower and described as his actual name, whereas I was described as the unnamed co-borrower. I was furious because I was the one who had applied for the mortgage, I was a current client of the bank and he wasn't, and I am the higher earner, but I was told, "this is France, madame".
It is definitely more socially conservative here and even among the young, liberal people I know, people will, for example, quite happily say they don't agree with gay marriage because France is a Catholic country, when France is actually supposed to be a secular country and those kinds of attitudes just wouldn't wash in the same social circles in the UK. I also notice that people use a lot of casually offensive language about minority groups which doesn't seem to bother people here but would be an absolute no-no in the UK.
I am straight and white and affluent and the "right kind of immigrant". As a British immigrant who does not hold French citizenship, I am quite sure people are more welcoming towards me than they are towards women of north African origin who were born here and have been citizens all their lives. I've also never had to access rape crisis services, or report domestic violence, and I'm not a lesbian. So I don't think I can really speak for all women.
That said, from my own personal experience things do seem pretty good here for women. Even in old fashioned male dominated industries like the one I work in, there are women in positions of power and they are respected. I do not think I am underpaid compared to my male colleagues at the same level; in fact, I believe I am actually paid more due to my unusual skill set and the fact that I would be more difficult to replace.
The legal abortion limit is much shorter - it was recently increased to 14 weeks from 12 weeks - but overall, women's healthcare is excellent here.
Maternity leave is short, and although you can extend it by taking parental leave which is remunerated at €400 a month, in practice most women don't, and if you are well paid, that represents a huge drop in your income. There certainly isn't a cultural expectation that women will stay off work for a year and be financially dependent on their partners. If anything it's the opposite; I am currently on maternity leave and will manage to take 8 months off, which is considered very long. The accessibility and affordability of high quality childcare from babies from 10 weeks to 3 years old - when school starts - is a real plus point. You don't have to use it, but it is available, you pay according to your means, and there aren't women in France who are stuck being SAHMs when they don't want to be because they can't afford childcare. If your income is low you pay next to nothing for childcare.
So yes, overall I think it is pretty good. Not perfect, but better than most places I think.
